AntiPhos 5000 ml salt water phosphate removal media, Aqualine Buschke. In the aquarium, excess phosphate results in over fertilization, leading to excessive algae growth. Antiphos rapidly absorbs phosphate. Antiphos is based on natural zeolite, which has been chemically changed so that it binds phosphate. When the material is saturated it should be removed, thus reducing and eventually eliminating the phosphate from the aquarium. 5000 ml for 250 gallons salt water.
